摘要:
An embodiment of the invention provides an ability to configure the dispatch policy in an application or transaction server. For servlets and JSP's this is configured on a per-URL (Uniform Resource Locator) basis, RMI and EJB it is configured on a per-method basis. Available dispatch options include the ability to execute the request in the same thread that read the request or to enqueue it on a queue which feeds a pool of worker threads. Using this configuration one can control various quality of service parameters of the requests. Requests may be expedited by executing them directly in the thread which read them, thus skipping the queue. Alternatively, some requests may be throttled by assigning them to a queue which is tended by only a limited number of threads.

In accordance with embodiments, there are provided mechanisms and methods for recovering from an incomplete transaction. These mechanisms and methods can enable embodiments to detect incomplete transactions when recovering from a server crash or other catastrophic event. Some embodiments can automatically re-establish interrupted connections when incomplete transactions have been detected. The ability of embodiments to detect incomplete transaction can allow recovery to initiate substantially immediately upon server restart and adapter redeployment.

In accordance with embodiments, there are provided mechanisms and methods for managing services in a communications network. These mechanisms and methods can enable embodiments to manage services provided by third party service providers, for example, to callers establishing communications sessions in a network. The ability of embodiments to control access to, and manage, third party services associated with communications sessions can enable embodiments to provide improved security and enhanced features to callers.

The invention herein provides a system for message encryption and signing within a transaction processing system. As disclosed herein the invention applies the operation of public key technology to transactional server security. Embodiments of the invention utilize a combination of message-based encryption and message-based digital signing, to ensure the security and authenticity of a message or message buffer sent from one party or process to another. Intermediate recipients may also inspect the message. The system described ensures the reliable authentication, confidentiality, integrity, and non-repudiation, of communicated messages.

The invention utilizes a personalization system that uses rules (110, 112, 113) to adjudicate and characterize a customer, or a customer's actions, and then to personalize a business function, such as a displayed page, based on the outcome of those rules. In one embodiment the invention provides a system for web-based personalization, that allows for personalizing the content or business functioning of a web-based application to reflect the characteristics of a particular user of said web-based application, said system comprising: a user profiler, for determining a snapshot of a particular user of a web-based application; a rules editor for inputting a set of rules governing the business functioning of said web-based application; a rules engine (102), that accepts input from said rules editor and said snapshot of said particular user, and uses said set of rules to make decisions about said particular user and the business functioning of said web-based application; and, a personalization processor that uses the output of said rules engine (102) to determine the content or business functioning of said web-based application as it applies to said particular user.

In an embodiment, a system for managing communications sessions is provided. The system embodiment includes a connection to a packet network that receives incoming calls. A stateful tier manages communications sessions established for the at least one incoming call. A stateless tier comprising one or more applications provides service(s) to the communications sessions in the stateful tier. One or more servers allocate and/or manage resources corresponding to the communications sessions established for the incoming calls in the stateful tier. The servers maintain the applications in the stateless tier for providing services to the communications sessions in the stateful tier.

A system and method for concentration and load-balancing of requests in a distributed computing environment. In accordance with an embodiment, a system and a method for reducing the number of connections in an Internet environment using one or a plurality of connection handlers which handle the connection from the client to the server, and a listener which determines which connection handler to use to handle the connection. Whereas prior solutions required a (n×m) number of connections to handle requests, the invention allows there to be only m connections which significantly reduces resource requirements and allows scalability.

摘要:
A system and method is provided for context propagation within application servers, message systems, and transaction-based systems Context Areas (136) allow users, both internal and external to the system, to associated information with an application which is then carried along with every request (144). Downstream components (148) can add to or modify this information, so that it can be carried back to the originator (130). Common use-cases for this functionality include diagnostics monitoring, application transactions, application load-balancing, and indeed any situation where information needs to be carried out-of-band. The ability to propagate out- of-band information prevents the pollution o fuser APIs and also allows the adding of information to read-only (i.e. 3rd-party) components. A system and method for context propagation in application servers and transaction-based systems.
